General Classification of (1,2) Parametric Surfaces in 葳3field by considering a dual scroll.We detect and describe (if it is not void) the trace of self-intersection and singular locus in the system of coordinates attached to the control polygon of a patch (1,2) in the box [0; 1] ˟ [0; 1].

Second, the singular structure of . = 0 is exploited, and the approximation problem is reduced to solving zero dimensional systems using Rational Univariate Representations. An experimental section illustrates the efficiency of the algorithm on Bézier patches.

Subdivision Methods for the Topology of 2d and 3d Implicit Curvescients.We report on implementation aspects and experimentations on 2d curves such as ridge curves or self intersection curves of parameterized surfaces, and on silhouette curves of implicit surfaces, showing the interesting practical behavior of this approach.
